THE FERN W^ORLD OF AUSTRALIA. 
47 
base nor the apex of the segment. Frequently met with on hill- 
sides or ranges of Southern Queensland, banks of Brisbane River, 
&c. ; also in similar places in N. S, Wales, Victoria and Tasmania ; 
rare in South Australia. 
P. marginata, Bory. Rhizome very thick, short and erect. 
Fronds having very stout stipites several feet in height, the main 
rhachis branched, usually tri-partite, each branch pinnate. Pinnge 
numerous., three to ten inches long, deeply pinnatifid ; segments 
oblong or broadly linear, often falcate, obtuse, quarter to one inch 
long., confluent into a winged rhachis two to three lines broad ; 
veins copiously anastomosing on each side of the mid-rib. Sori 
often continued round the sinus, but rarely reaching the ends of the 
lobes. Barren fronds thinner, the lobes often minutely dentate. 
One of the handsomest of all the Queensland ferns, generally met 
with in the tropical scrubs. 
P. comans, Forst. This fern is said to be near P. marginata 
but more branched. Secondary pinnae four to ten inches long, deeply 
pinnatifid ; segments numerous, half to two inches long, oblong- 
lanceolate or linear, often falcate, decurrent along the rhachis which 
is not, however, uniformly winged as in P. marginata ; some of the 
lower segments sometimes again shortly pinnatifid ; veins copiously 
reticulate. Sori usually continued round the sinus, but rarely to 
the tips of the lobes. Barren segments or barren tips of the fertile 
ones usually dentate. South Queensland, IM. S. Wales, Victoria 
and Tasmania. 
, XXIV. LOMARIA, WiLLD. 
Rhizome creeping, or in some caudiciform. Fronds pinnate, 
pinnatifid or entire ^ the first of each year's growth usually barren, 
the inner fertile ones with linear pinnules, sometimes a few sterile 
abbreviated pinnae or lobes at the base of fertile frond. Sori in a 
continuous line on each side of the costule, between it and the 
margin, and opening on the inner side next the costule, the sori at 
length covering almost the whole of the under surface. Veins of 
the barren pinnules transverse or oblique on the costule, mostly 
forked. Name from loma, a fringe, in allusion to the scarious in- 
dusium. 
L. Patersoni, Spreng. Rhizome short, thick, ascending. 
Fronds variable, from a few inches to two feet high, stipes short 
scaly, entire or pinnatifid with few or several linear segments three 
to six inches long, more or less decurrent on the rachis and stipes, 
those of the barren frond half to one inch broad, the veins trans- 
verse; segments of the fertile fronds as long but only one to two 
lines broad, the sori at length covering the whole under surface. 
Like others of this genus the lower portions of the fertile frond, 
or at times one side, sterile. Common in the dense scrubs of 
tropicul Queensland, also at Maroochie, and again in several loca- 
lities in Southern Queensland ; plentiful also in S. Wales, Vic- 
toria and Tasmania.
